IMPRovEMENT IN sTuDs. 0R BUTTONS.

Speeication forming part of Letters Patent No. l 78,842, dated J une'20,1876; application tiled T0 all whom it may concern: t

Be it known that I, WILLIAM R. DU'IEMPLE,

. l of Providence, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Studs or Buttons;and I do hereby declare that the followingi's a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawing,formingav part of this specitication.

vMy invention vconsists `in the improvement of shirt buttons or studs,as hereinafter fully described, and pointed out in the claim.

In the accompanying drawing, Figure 1 represents a perspective View,with portion ot' back removed, ot' a studor button constructed accordingto my improvement. Fig. 2 is the front and post. Fig. 3 is the back andsec-V tion. Fig. 4 is a plan ot' front. Fig. 5 is a planet' back. Fig. 6ijs un enlarged section 0n lines :1; zr, showing post D locked. Fig. 7is a section on lines :c al', with the post D partially turned, inposition for unlocking. Fig. 8 is the piece 0.

Similar letters of reference indicate corresponding parts.

A and B are the front and ba'ck of t-he stud or button. D is a roundpost, soldered tothe front A. C is a tube, solderedto the back B. Thepost D is cut from its surface to center, apart of its length, to formthe iiat 1L. d is a notch cnt at right angles to the post D,

' and at an angle of about thirty degrees to the iiat h. chamfered at s.

is made the right thickness tofit easilyY the notch d. This piece isinserted and soldered in the side ofthe tube O, iilling about onehalt'its diameter, at the proper place to engage the notch d when the buttonis locked.

Aportion of the tube C is removed at e, to.

allow the spring 'r to rest on the fiat 7L ot' the -postD when said postis inpositiou. The

spring r is made circular, one end resting against the tube G, theothers soldered to the back B.

Insert the post D in the Vtube C; turn until the'iiat h passes the pieceo; then press the front and back together; the cha-intere presses thespring out, allowing the post to pass, when the recoil ot' the springturns the post D, thereby engaging the piece 0 with the notch (l, whichsecurely fastens the front vand back Hold the back B, and turn the frontA in the direction, of the arrow; this will disengage the piece o fromthe notch d, and the post D may be withdrawn t'roin the tube C.

Having thus described my invention, what I claim as new, and -desire tosecure by Letters Patent, is-

Ilhe improved stud or button herein described, consistiug of thefrontdisk A, having adapted to be united -in the manner and for the purposespecified.
